Use Cloze's Mail Merge feature to email multiple people at once, but in a personalized manner. It is designed to let you communicate at scale with your real email while maintaining the one-to-one, personal touch of each relationship.
You will start by composing the base message you want to send to everyone, optionally you can personalize it for each contact, and then tap on the send button to send your email to each recipient.
A personalized greeting is automatically included for each recipient.
No one is BCC'd. Each person receives their own unique email. Each person will not see the other recipients.
